8GB DDR4 2400MHz CL17 Desktop Module

This A-Tech module provides 8GB of DDR4 memory at 2400MHz with a CL17 latency rating. It is an unbuffered, non-ECC DIMM designed as a direct replacement for specific Corsair part numbers. The module operates at the standard DDR4 voltage of 1.20V and uses a 288-pin connector for desktop motherboards. It carries no heat spreader and is intended for general desktop memory upgrades.

Who This Suits and Who Should Look Elsewhere

This module suits owners of desktops that require DDR4 2400MHz SODIMM memory and specifically need to replace Corsair CMK32GX4M4A2400C16, CMK16GX4M2A2400C16 or CMK16GX4M2A2400C16R kits. It is not suitable for laptops or small form factor systems that require 262-pin SODIMM modules. Buyers needing ECC, registered memory, lower latency CL16 or speeds above 2400MHz should select a different part.

The Deciding Specification

The critical specification is the 288-pin DIMM form factor combined with DDR4 2400MHz speed and CL17 timing. Your motherboard must support DDR4 unbuffered non-ECC memory at this frequency and accept 288-pin modules. Verify your system documentation for maximum supported capacity per slot and qualified vendor lists before purchase.

Questions about this item

Will the CL17 CAS latency become the bottleneck during long rendering sessions?

The module runs at CL17, so latency stays fixed at that value regardless of workload length.

How much heat does an 8 GB stick without a spreader produce at 1.20 V all day?

At standard 1.20 V DDR4 voltage and no heat spreader, the module relies on case airflow; it runs cool enough for typical desktop use.

Does my motherboard need a 288-pin DDR4 slot to accept this DIMM?

Yes, it is a 288-pin DDR4 UDIMM and requires a matching DDR4 DIMM socket.
